As you can see from the video below, RIM has taken another small step away from the very businessy reputation of the BlackBerry, adding a dedicated YouTube application as well as a cover flow-like UI for music and media. You've also got a new WebKit browser with tabs support and a new quick menu for contacts, you just select a contact and then it brings up options to email, SMS, call, etc. There's an integrated stream that aggregates all updates from across your social networks, something that will prove popular with the web 2.0 people. There's also what looks like a new on screen keyboard though there's no telling if it's the ever so annoying tactile-touch present in the BlackBerry Storm.
Check the video below. You might need to watch it a couple of times to really see what's happening. The preview is done as a semi-transparent overlay with faceless people dancing in the background to the Black Eyed Peas; it's hard to watch the demo when there's a girl shaking what God gave her right behind it. It gets easier at 00:57 when she switches with a guy in a suit who's constantly fixing his tie and patting his lapels.
